I cannot get to my trial of Photoshop because I need to enter a path (ippcvn8.dll). Where and/or how do I do that? I am using Windows 10
More than likely your CPU is not supported
Not sure what dll's you're referring too, bottom line is your PC is under powered to run the most recent version of Photoshop
If your CPU does not support SSE 4.2 or later, you will have to install Photoshop 2021.

Also see https://answers.microsoft.com/en-us/windows/forum/apps_windows_10-photos/where-can-i-get-ippcvn8dll-... because Microsoft's forums confirms Ged's information.
Right 2020, Ged. So 2020 is not availiable as a trial? Sorry, I did not know.
